A small hard plastic container (the plans recommended a bottle from photo-chemicals) some vacuum line, a valve, and an aquarium bubble stone. Air is sucked through the tubing through the bubble stone (which is submerged in the water in the container) and then through another vacuum line (with the valve on it) in to the engine. None of the containers i could easily lay hands on would hold up to the vacuum. |
I just "Steam Cleaned" mine today... used one gallon of distilled water through the two UIM nipples that's T'd off using a vaccum hose. It didn't take but 5-7 mins to go through the whole gallon
I didn't notice anything really significant other than it revs a lot more smoother through the powerband and revs a little quicker.... It also idles a tad smoother as well.... I also added a can of Seafoam (gas tank) afterwards and drove it around... Although I think I should've added the Seafoam first... |
Did a gallon for each rotor today. Did not notice any improvement. Couldnt hurt I guess. G

Why would they have vacuum on them? Wouldn't they have to be vented to allow the water to be drawn into the engine?

I was trying to gather some information about steam cleaning, and I dug up that old topic
https://www.rx7club.com/showthread.p...ht=steam+clean As I can see it's dated 2004... What this guy says is pretty scary, I was wondering has this been proven wrong up until now? |

In regards to his argument that the remaining carbon deposits left behind will act as a form of sand paper and cause premature wear and grooves in the sidewalls -- I can not deny or support this with any personal evidence but IMO, this seems like a bogus assumption. I did the steam cleaning procedure on my engine a while back and it increased the compression on the front and rear rotors by at least 10 psi - so from a personal experience stand point, it worked wonders for me. |
If I already have water meth injection on my car should I still do a steam clean at clost to 10K miles? Thanks!
|
No. There's probably no need.
|
Well I did it today and bloody hell.... I must've gained almost 12 in the rear and 15 in the front... didn't turn the car off for 3 min after.. killed it.. and then started it up and let her idle for about 10 min and turned it off. Going to do an oil chance if I get a chance by wed, then i'll take it out and see if I can notice the difference.... But it already rev's a whole lot smoother..
|
Also I didn't seem to see anything Glowing Red hot... But I couldn't believe how much compression I picked up... I had to do each housing twice because I was so shocked...

Ok I see Azcamel posted about water in his oil also in this thread. https://www.rx7club.com/general-rotary-tech-support-11/water-instead-atf-decarboning-42318/page4/

Yea remember to change your oil some time soon after you do the steam cleaning method. The reason I say this is because when I did this some time ago I changed my oil and there was some water in my oil which I noticed when I drained it to a container. As for me I really don’t like water in my oil. Has any one else noticed water in your oil when you changed it after doing this?

I just changed my oil yesterday... ill wait till its around time again before I try this steam cleaning. I am about to park the 7 again to bang out the body. and after that a tune. so its a perfect time. will post compression numbers before + after.

Cool cool..... my compression was 97 in the rear and 94 in the front before the steam clean. After my steam clean both were well over 115... i'll do another check in about a month or so just to see if it's stayed the same. but as of right now I couldn't be happier.
if my engine blows up, i guess well all have our answer. |
I would love to see actual before and after compression numbers from people to accurately judge just how effective this is.

I predict that no one will be able to top the results that have already been reported.

did an oil change this morning as planned. Oil smelt like Gas as usual...but there wasn't much water in it that I could see as it would be seperated in droplets im guessing. There was a little bit of water on the underside of my oil filler cap and on my dip stick but thats about it. ALl I know is I took her for a drive today through the canyon and the car ran gorgeously. Much smoother than before...

The 'before to after' increase of compression that your reporting would have nothing to do with the "tune", "set-up" or after driving a few miles in between compression tests.
I'm a believer in water injection. I've done it myself a few times over the years...just never with your remarkable results. And with the installation of AI, I don't anticipate a need to do it the "old fashion way" anymore. My feeling is it's also marginally riskier to do an "all at once" water ingestion vs. AI... and you don't have the other benefits. |

as long as I dont kill it or lose compression |
